The song is being released ahead of next month's Olympics and Perry says NBC has chosen to use it as an anthem for the Rio Games. Perry has also put out a video for the song featuring Olympic athletes, including Gabrielle Douglas, Michael Phelps and Usain Bolt.

Perry explains in a statement that she released the song now instead of waiting for her next album because there's "a need for the world to unite." She says she can't think of a better example of coming together than the Olympic athletes.
